properties

The navigator now displays all properties whose type is a sub class
of QGraphicsObject, except for those properties inherited by Qt/Item.
The contents of the default property are displayed as direct children
of the model node's tree node.
Reparenting into and from the displayed properties is supported.

After this change, the parent properties of model nodes do not have
to be "data" or "children" anymore. Any node or node list property
can contain children.

I did some changes to the patch.
1.) Fix for NodeMetaInfo
2.) Remove changes to ObjectNodeInstance
3.) Adapt QmlObjectNode

When the user moves a block up or down the text markers have to be
updated correctly.
This is done now in moveLineUpDown().
We check if a text marker is in the block that is about to be moved and
set the position of the QTextCursor to the correct value, afterwards.
